MERRITT BRADFORD SCOTT, OF HARTFORD, CONNECTICUT.

COLLAR-BUTTON.

SPECIFICATION forming part of Letters Patent No. 328,721, dated October 20, 1885. Application filed July 6, 1885. Serial No. 170,729. (No model.)

To all whom it may concern:

Be it known that I, MERRI'rr B. Score of Hartford, in the county of Hartford and State of Connecticut, have invented new and useful Improvements in Collar- Buttons; and I do hereby declare that the following is a full and accurate description of the same, reference being had to the accompanying drawings, wherein- Figure 1 represents in perspective the several parts of my button detached. Fig. 2 is a transverse section of the button complete. Fig. 3 is a longitudinal central section of the same in use.

My invention consists in a collar-button provided with a post invariable in length and a sharp-pointed stud or pin adapted to travel therein and to be projected therefrom into the material of the necktie to keep the same from moving up or down after it has been adjusted in place.

A and B are respectively the top and shoe of the button. The top A is provided with a tubular post, d, provided with one or more slits, 0, preferably two, on opposite sides of said post, and a central orifice, g. The shoe B is provided with a tubular post, it, having a screw-thread cut in its inner surface. Said shoe may have a central orifice full size of the interior of the post h. The post h is sufficiently large to pass over and inclose the post (Z.

A runner, I, fitted to enter the slits e, and provided on its edges with sections of screwthread fitted to traverse the internal threads of the post h,is also provided, and the pointed stud or pin it is attached to said runner.

In assembling the parts the runner may be put in place in the slit 6, and the post d then soldered fast to the top A. The post h having in like manner been soldered to the shoe B, the post (i is slipped into the post h and the runner engaged with the screw-threads in said post h by revolving the post 1 therein. When the end of the hollow post at has been projected through the shoe B, the extremity of d is milled or turned over, as shown at q, and the parts are thereby united with freedom of relative revolution, and when the top and shoe are revolved relatively as to each other, the runner is caused to move along the slit c,and consequently the sharp stud or pin will be thrust out of or withdrawn into the button,as the case may be.

The manner of use is obvious. The button is inserted in the button-hole of the shirt-band 0' in front in the usual manner. The necktie T is adjusted and then the pin is thrust out so that its point will penetrate the material of the tie, and thereafter prevent it from changing its position.

Having described my invention, I claim 1. A collar-button having a hollow fixed post provided with an interior screw-thread, combined with a sharp-pointed stud or pin mounted on a runner in engagement with said screw-thread, and moved forward or backward when rotated, to be concealed or thrust out, as set forth.

2. In a collar-button, the top A, with its slitted post d, fitted to enter and revolve within the tubular post h, which is secured to the shoe B, and is provided with an internal screw-thread, combined with the runner I, fitted to rest and move in the slitted post d, and provided with a screw-thread adapted to engage the screw-thread in the post h, and the sharp-pointed stud or pin 70, mounted on said runner, whereby a relative revolution of said top and shoe will cause said pin to be withdrawn or thrust out, as set forth.
